1. Meiosis is important to the reproduction of organisms. Meiosis prevents the accumulation of
extra genetic material by producing A haploid gamete cells
C genetically identical daughter cells
B mutations that destroy extra DNA
D offspring through asexual reproduction
2. Meiosis benefits a population by allowing for sexual reproduction. Unlike asexual
reproduction, sexual reproduction actively increases the amount of –
A autosomal DNA
C genetic variations
B available nutrients
D dominant alleles
3. Animals that reproduce sexually differ from animals that reproduce asexually in that sexually
reproducing animals have
A a larger number of offspring
B more genetic variation among their offspring
C offspring that are nearly identical to their parents
D offspring that are perfectly adapted to their parent’s habitat

4. The final products of meiosis are A haploid cells.
B triploid cells.
C diploid cells.
D polyploid cells.
5. Which situation is a result of crossing-over during meiosis?
A Genes are duplicated exactly, ensuring that offspring will be identical to the parents.
B Chromatids thicken and align themselves, helping to ensure genetic continuity.
C Genes are rearranged, increasing the variability of offspring.
D Chromatids fail to sort independently, creating abnormal chromosome numbers.
6. Which statement about the offspring that result from sexual reproduction is generally true?
A The offspring show genetic variation from their parents.
B The offspring have genetic material identical to that of one another.
C The offspring have genetic material identical to that of one of the parents.
D The offspring have twice as much genetic material as each parent.
7. Meiosis is significant within a population because it increases the –
A number of mature males
C amount of genetically modified organisms
B genetic variations in the population
D number of new alleles available
8. The process of meiosis directly leads to an increase in which of the following?
A dominant traits
B size of gametes
C triploid offspring D genetic variation
